Efficient encoding of control signaling for communication systems with scheduling and link

摘要

The invention relates to a method of sending control information from a first node to a second node in a communications system providing a plurality of resource units for the transmission of data. The control information is sent by use of a code book comprising at least one code word identifying control information relating to data transmission over a resource unit. The code book is dynamically updated by means of repeatedly transmitting an updated version of code book information from the first node to the second node. The invention also relates to a first communications node comprising means for transmitting control information to a second node. The means for transmitting control information is adapted to transmitting the control information by use of a code book; and to repeatedly transmitting an updated version of code book information in order to achieve that the code book is dynamic.
